8. For each d in varDeclarations, in reverse list order do
|
|
a. If d is neither a VariableDeclaration or a ForBinding, then
|
|
i. Assert: d is either a FunctionDeclaration or a GeneratorDeclaration.
|
|
ii. NOTE If there are multiple FunctionDeclarations for the same name,
|
|
the last declaration is used.
|
|
iii. Let fn be the sole element of the BoundNames of d.
|
|
iv. If fn is not an element of declaredFunctionNames, then
|
|
1. If varEnvRec is a global Environment Record, then
|
|
a. Let fnDefinable be varEnvRec.CanDeclareGlobalFunction(fn).
|
|
b. ReturnIfAbrupt(fnDefinable).
|
|
c. If fnDefinable is false, throw TypeError exception.
